Abstract

A system and process for unwinding rolls of material is disclosed. The system is particularly well suited for unwinding soft, high-bulk tissue webs. In one embodiment, the system includes the combination of a center unwind device and a surface unwind device to unwind the roll of material in a primary unwind location. Once the roll of material is partially unwound, the roll is then moved to a secondary unwind location while a new roll of material is moved into the primary unwind location. In this manner, multiple rolls of material can be continuously unwound without substantial downtime.
